AU-220M 57mm automatic cannon unmanned turret

The turret is called AU-220. It’s been initially developed as an upgrade to the PT-76 amphibious tank to replace its 76mm main gun and old turret.

The Central Research Institute Burevestnik-designed 57-mm A-220M gun, designed for use by armored vehicles.

An upgraded PT-76 is shown with the 57mm AU-220 turret.

57mm Gun

The 57mm gun that’s also used in Atom 8×8 is basically an Anti-Aircraft gun used in S-60 towed AA system. The gun was developed in 1950’s.
The 57-mm anti-tank gun model 1941 (ZiS-2) developed and adopted in the opening days of the Great World War.
The same cannon also used in ZSU-57-2 Soviet self propelled anti-aircraft gun

Burevestnik’s 57 mm А-220М naval artillery module, from which the AU-220M was effectively reverse engineered.

The cannon uses 57x347mm semi-rimmed ammunition. The image below shows the 57mm ammunition vs the Bofors 40×365 ammunition.

The gun is recoil operated. Rate of fire is 105-120 rpm and the muzzle velocity is around 1.020 m/sec. It has a barrel length of around 4.4m.
 
The effective firing range against ground targets is 4km’s.
 
The gun has a new automatic loading capable ammunition feed system that houses 20 ready-to-fire rounds as shown below.
The turret basket has a powered 73 round ammunition carousel that provides ammunition to the linkless feeder above.
The 57mm gun with the AP round has a penetration capability of 130mm of Steel at a range of 1.000m. I would expect the penetration would be much better for the huge 57mm caliber.
 
The 35mm APFSDS round has 120mm penetration at the same range.
